RADIATOR CONSTRUCTION.

Application iled April 2, 1924. Serial No. 703,637.

To all/whom t may concern:

Be it known that I, JOSEPH H. BiusKlN,

a citizen of the United States, residing at Los Angeles, inthe county ofLos Angeles -and State of California, have invented new and usefulImprovements in Radiator Constructions, of which the following is aspeciication.

My invention relates to radiator core construction and consists o thenovel features herein shown, described and claimed.

An object of my invention is to make a radiator core construction .inwhich each water tube is formed of two pieces of thin metal having plainzig-zag bends, the metal of the two pieces fitting closely togetheralong their slde margins and the metal of the two pieces beingoppositely bulged outwardly ,between the close fitting margins to formthe water space.

Another object is to space the water tubes with a single sheet of metalhaving margins fitting the margins of the water tubes and the spacerbeing formed of ver thin metal transversely cut in places and aving mainzigzag bends corresponding to the zig-zag bends of the water tubes andhaving small reverse bends parallel with the main bends and extendingbetween the transverse cuts so as to form sheets in which the edges ofthe water tubes will fit and so as to form the greatest practical amountof opposing lines to produce stiffness of the spacing plece to resistcollapsing of the water tubes towards each other, the transverse cutsroducing round edges or fins to serve as anges :for stiffening the edgesalong the cuts and to make a resistance to the air.

Other objects and advantages will appear from the drawings andspecifications.

The drawings illustrate the invention.

The details of the radiator core construction shown in the drawings areas follows:

Referring to Figs. 1l, 12, 13 and 14, the

water tube plate 1 is long enough to make,

one side of a Water tube having zig-'zag bends and extending from thebottom of a radiator to the top. lThe side margins 2'.

and 3 of the plate are smoothly and evenly bent zig-zag so that themargin of one plate will fit closely against the margin of the otherplate. The figures show the construe tion upon an enlarged scale. Theintermediate portion 4 between the margins 2 and 3 is bulged in onedirection thruout the plate so that when two plates are placed togetherwith the bulging portions 4 outward a water space 5 is formed.. Informing the zig-zag bends, alternate bends 6 are formed to produce sharpstraight edges and the other plate 1 is placed in position with the'sharp bends 7 are rounded so that when the two bends 6 in the grooves14.

In a like manner a second sheet metal of the samewidth as the water spacer 8 is placed in position with the sharp tubeplate 1 and has margins 9 and 10 bent bends 6 in the grooves 13 and 14and the smoothly zig-zag to match the bends of the a'pper ends of theplates 1 folded together water tube plate and adapted to fit against toproduce another ridge 30, and in this the margins of the water tubeplates in spots manner a radiator core may be built up to 11 and 12.Asmall groove 13 extends fromv any desired size and shape and after thethe spot 11 of one margin to the spot 11 of parts are properlyassembled, cleaned and the other margin, and in forming the treatedvwith iux, the entire core may be groovesthe metal is reversely bent onlines submerged in hot solder or the like, and all parallel with theother bends.
